We've been doing a bit of tinkering with our Pulse Rifles down here at KGB.
Beyond fitting a MOSFET, a 1J spring and a new hop rubber.... We've also managed to shoe-horn in an 11.1v LiPo battery.
Now, I'll start by saying that this mod requires you to split the Snow Wolf M41A body down and gain access to the grenade launcher case and once it's in, the battery is not removable and charging is accessed via the faux loading tray underneath.
If you're happy with this... then game on.
If not... I'd stop reading now.
The battery.... It's an 11.1v LiPo
It's the 10th one down on this page... (sorry I can't link to it directly).http://www.component-shop.co.uk/html/11 ... packs.html
The wiring stays pretty much in the same place, although we changed the connectors for DEANS for better connectivity and you may have to move the fuse out of the way slightly.
The battery was placed in the shotgun housing
It sits about here...
We had to break off a few moulding tabs inside the housing to get it to fit but nothing serious. The battery itself is a perfect fit for the area it needed to sit in.
It is permanently fixed inside the shotgun housing (the shotgun racking function still works), and the battery connectors and recharging are accessed by a neat moveable shotgun loading port that slides back to reveal all the wiring etc.
The orientation of the battery is biased so the connectors and all that gubbins sit towards the front of the rifle. This is conveniently in the same place as where you would have the standard connector.
The loading tray is sat on two rails inside the grenade housing. We took out a little bit of the material at the rear of this tray and it allowed the faux tray bit to slide back and forth. Proph added a small screw in here to give you something to grab hold of.
This can be opened to reveal all the wires. They can be connected and stuffed back in and the tray closed in to make it all neat again.
The battery is a bit of a beast and should be able to handle even a hard days airsofting.
The joy of a LiPo is that they have a very high discharge rate and as such they can supply the rifle with all the juice it needs, rather than the motor trying to suck out the power.
As a result, the battery last comparatively longer than a NiCd or NiMh type battery with a similar Amp/hour rating.
Plus for the given rating of the battery, LiPo's squeeze more juice into a smaller package. Very good when you're limited on space.
Only word of warning... when using such a high voltage battery, it is advised to switch to a MOSFET to protect your trigger contacts from arcing.
A nice skirmish worthy weapon now.
